Practice Relating to Rule 68. Precautions while Receiving Parlementaires
New Zealand’s Military Manual (1992) states:
The belligerent to whom a parlementaire
is proceeding may take all steps necessary to protect the safety of his position or unit and to prevent the parlementaire from taking advantage of his visit to secure information. The adverse Party may prescribe the route to be taken by the parlementaire or may bind his eyes, may limit the size of the party or take similar action.
